In right “Live CNN” panel, Trumps clearly start clapping when singing stops (0:34 - 0:36) (watch short clip from the beginning, you can easily identify where the Trumps are)
In left “Live CNN” panel, Trumps appear to be sitting there like elite snobs and are only shown to start clapping at 0:41, 5-6 seconds later.
CNN trying to make the Trumps appear to be snubbing the singer.
Left panel clearly delayed to make the Trumps look bad.
Not all church congregations appreciate clapping after hymns, thinking it is not appropriate. I can’t ever remember that happening in the church where I grew up. It is good manners to see what the regular churchgoers do before jumping in.
